Be it known that I, FRANK. CHASE, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and use-` ful Improvements in Machines for Uniting the Soles and Uppers'of Bootsand Shoes, of which the following is a specification.

In another application for Letters Patent, led September 17, 1883,-a`nd bearingtheserial number 106,686, I* have described and claimed a method of Auniting the uppers and soles of boots and shoes, which consists in form- -ingholes `in the parts to be united by punching out or removing portions of the same, and then forcing the removed portions or cores back into the holes,`carrying with them the cord or thread previously laid over or across `said soles, thus forminga continuous line of fastenings.

My present invention is directed to a machine which is adapted to perform the abovenamed series of operations; and itis characterized mainly by "the combination, with a punch and a driver, of a cord or thread guide arranged and operating automatically and at the `proper times, on the one hand, to remove the thread from the path of movement of the gpunch, so as to permit the latter to punch out from theparts the requisitecore or plug, and, on the other hand, to presentthc thread over the hole thus formed to the driver, which, in its descent, forces the core or plug out from the punch upomthe thread and down into the Fig. 3 isla plan ofthe thread-guide detached.

Fig. 4 is a plan of the lever by which said guide is operated.

A is the frame or goose-neck which supports the working parts.

Bis a head, which carries the punch, driver,

j and antomaticallyoperating thread-guide, and

which is"attachedto the front of the goose-neck A. The head is .preferably connected to Aby a pin or trnnnion, a, which will permit it to oscillate slightly, so as to adapt itself `to the movements of the vibratory levers which op crate the punch and driver.

Gis the punch, which is tubular, and is constock D', which takes its bearing and is adapted toV slide up and down in the tubular punchstock. AMotion is transmitted to the various parts from a driving-shaft, E, supported in bearings inthe goose-neck A, on the front end of which shaft `is the cam-disk E, provided with acampath, l), (seen in dotted lines in Fig. 2,) which is entered by studs c l on the driver-operating lever-F and punch-operating lever G, respectively.

F is a bell-crank or elbow lever pivoted at c to the frame of the machine, and connected by a link, f, to the upper end of the driverstock D', which latter passes out through the upper end ofthe punch-stock, and also through the punch-operating lever G. Lever G is a straight lever, pivoted to the frame at g, and connected by ball-and-socket `or equivalent joint, 7L, to the top of the punch-stoclvG. Inasmuch as it is requisite that the punch should make a deeper cut in some'portions of the shoe than in others-for instance, in that portion where it goes through the heel-stiffener before reaching theinsole-I make its f'ulcrumpin g adjustable up and down, for which purpose the pin g, on which the lever G turns, is eccentric to the stem or hub g', which turns in the frame. On the end of hub g is a handle, g2, by means of which the hub can be rotated so as to set g up or down, as desired. The

fulcrnm-pin can be heldin its adjusted position by means of asuitable clamp or retaining device, which I have not deemed it necessary to represent, inasmuch as such devices are well known to the skilledimechanic.

The thread-guide hereinbefore mentionedVV IOO v rises, the thread-guide pinion makes a quarterter with a hole, t", of proper size and form to permit the passage of the punch. rIhis pinion is provided with an eye or aperture, 2,'for the passage of the thread or cord x, which latter passes from a bobbin or spool on the framev A, through anweye or opening in the head-B, down through the aperture it in the pinion, and thence down and out through the opening j vin the bottom of the head. The thread-guide pinion i is operated by a pinion, 7s, also seatedY in the base of the head B. rIhe pinion last named is actuated by a vertical spindle, Z, whose squared lower end enters a similarlyshaped socket in the pinion, and 'whose upper portion, which is of angular cross-section, and at the proper point has a quarter twist or turn, Z', passes through an opening or eye, m, of shape corresponding to the cross-section of the spindle in the outer overhanging end of the driver-actuating lever F. Then the machine is in operation, the lever, as it passes up and down over the turn Z, will rotate the spindle a quarter-revolution alternately in opposite directions, which will impart corresponding movements to the thread-guide pinion z. rlhe normal position of the pinion is such ihat its thread-eye it occupies a position in which the thread from it will pass across directly below and in the path of movement ofthe punch or driver. A quarter-turn of the pinion from this position will carry the thread out of or io one side of the path of movement, so that by alternating movements of the pinion the thread will be thrown into and out of the path of the driver and punch.

In connection with the parts of the machine thus far described I employ in practice a jack, Y, on which the lasted boot or shoe Y is pre.- sented.

The parts are so arranged and timed in their movements that when the machine is in motion they operate as follows: Wvhen the parts are in the position shown in Figs. 2 and 3,-the thread-guide pinion is so placed that the thread is to one side of the path of the punch. Vhen the driving-shaft is put in motion, the camdisk revolving in the direction of the arrow in Fig. 2, first the punch descends, punches out from the work'Y the core or plug, and rises, carrying with it said plug, the pinion z' makes a quarter-turn, so asto bring the thread across the hole thus made in the work, and the driver descends and forces the plug out from the punch upon the overlaid thread and forcesV both plug and thread down into the work into the hole out by the punch. The driver then turn in the direction requisite to carry the thread to one side of lthe path of the punch, the work is fed along, and the series of operations just described are repeated lin order stated.

Vith a view to causing the thread to tail7 to one side or the other, according to the direction in which the last may be moved, I form the eye min a hub or block, m', provided with a handle, mi, and so mounted in the end of lever F as to be capable of rotating therein, a spring-catch of any suitable construction being provided for the purpose of locking it in position at each half-revolution. In order to make the thread tail in the opposite direction from that shown in Fig. 3,' the hub m should be given a half -turn, thus giving a half-turn to the guide-pinion i'. l

Having described my improvements and the manner in which the same are or may be earried into effect, what I claim as new and of my invention isl. The combination, with thepunch and the driver, of the cord or thread guide arranged and operating automatically and at the proper times to' remove the thread fromthe path of the punch and to present it to the driver, substantially as and for the purposes hereinbefore set forth.

2. The tubular punch, and the driver arranged within the punch, and operating to eX- pel therefrom the core or plug cut out from the work, in combination with the thread-guide andthread-guide-operatingmechanism,where by the said guide is operated alternately to carry the thread out of the path ofthe descending punch and into the path of the descending driver, substantially as and for the purposes hereinbefore set forth.

3. The combination, with the punch and punch stock, of the punch actuating lever supported upon a fulcrum adjustable for the purpose ot' Varying the depth of cut made by the punch, substantially as hereinbefore set forth.

4. The reciprocating tubular punch, the independent reciprocating driver contained in said punch, and the thread-guide, in combination with the head B, swiveled to the frame of the machine, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 14th day of November, 1883.

FRANK. CHASE.
